Advertising models really do matter for sportswear

I thought the MLB brand was just mediocre clothing aside from their baseball caps, but seeing Karina in that short puffer jacket makes the entire brand look hip and trendy.
Since it's unisex, I'm really tempted to buy it.
Other outdoor brands like Eider, K2, Nepa, and Discovery also seem to produce good-looking clothes because they use idols or young actors as their models.
